My invention relates to improvements in methods of manufacturing shoes with adhesively attached soles, and the object of the invention is to devise a method which will 5 enable soles to be cemented to the tapes secured to the lower marginal edge of uppers in the case where the last employed has its lower surface arched for use in manufacturing a shoe with a heel in contradistinction to a last with a flat lower surface used in the manufacture of shoes or slippers'without heels.

Hitherto in manufacturing shoes and slippers with cemented on outer soles, a method has been evolved and is used extensively wherein the lower marginal edge of the upper is not inturned, but is replaced'by a flexible inturned tape with a draw string. In the manufacture of fiat soled shoes and slippers this is an eminently satisfactory and economical method where the shoe is made to fit both the right or left foot as'thetape can be drawn tight by the drawstring and does not pucker as does the less flexible upper when inturned. The above method is not, however, susceptible to use in the manufac'ture of shoes with-arched soles wherein a shank is inserted, for. the reason that in drawing the/tape taut over a last with an will gape at such arched portion an will not lie close to the last. Such theit is impossible to cement the so e satisfactorilytothetapet'- By my method such disadvan is overcome and the outer sole can be fir y secured to the tape as such tape will liesnugly against the last. Co uently the finished shoe will )conform identlcally t0 the shape of such last. Even in the case of afshoe with a flat'sole manufactured to fit either a right or a left foot the existing method above described can not be used as the tape will gape from the last on the inner side of the sh0e ,whereas by my method this disadvantage is overcome.

In carrying out m method I provide means for securing the tape to the shoe shank usually employed in shoes with arched soles at that part 0 the shank which is m the vicinity of the arched portion of the shoe. This will hold the tape in snugly against the last and will not allow it to arched lower surface or sole portioni the tape .with a plurality tween the tape pe. In the manufacture of flat sole shoes provide a shank which is not ordinarily with the tape method. Referring to the drawings Fig. 1 re resents. an inverted plan view.
